Comparison of biogenic amine and polyphenol profiles of grape berries and wines obtained following conventional, organic and biodynamic agricultural and oenological practices
No full textThe bio-active compounds present in food and beverages have a high potential influence on the future
health of humans. The levels of biogenic amines, anthocyanins, polyphenols and antioxidant activity were
measured in white (Pignoletto) and red (Sangiovese) grape berries and wines from the Emilia-Romagna
region (Italy) obtained following conventional, organic and biodynamic agricultural and oenological practices.
No significant difference was shown among the samples coming from different agricultural and
winemaking practices. Principal Component Analysis was also performed. Biogenic amine amounts were
higher in red than in white berries, while in the wines an opposite trend was observed, with histamine,
tyramine and putrescine being the most abundant in Pignoletto wines. Red grapes and wines were richer
in anthocyanins and showed higher antioxidant activity than white ones. The total level of polyphenols
was similar in red and white berries, but with different metabolite profiles depending on the grape variety

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
